Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a buoyant structure for floating structures,

The present invention relates to a buoyant body construction method for a floating structure. More specifically, it relates to a method for constructing a buoyant body for a floating structure that is more economical and stable because a large-scale floating structure can be stably installed in the sea.

FIG. 1A is a conventional PE Pultun 50 construction photograph. FIG.

In other words, it is possible to identify PE Pultun 50 connected to support a bottom plate in a floating bridge such as a marina or a pier at sea.

Such conventional PE puntoons 50 are assembled by connecting means as a kind of PE box body, and are light in weight, which is advantageous in manufacturing, transportation and installation.

However, the conventional PE Pultun 50 is unsuitable for use as a support for supporting a maritime floating structure constructed by concrete on the sea, and there is a method of making a large PE Pultun 50, but this is not economical. Is not easy.

FIG. 1B is a photograph of the concrete of concrete manufactured by using concrete.

In other words, the conventional PE Pultun has a limitation to support a large overhead load, so it can be said that Pultun is made of concrete. Although concrete can be made of cast concrete, the concrete can be manufactured by using precast concrete which is usually transportable.

In this way, concrete made of concrete connected to each other at sea is connected to each other by means of connecting means. Such connecting means is a possibility of damage at the connection portion of Pultun which is made of heavy concrete, There is a problem that efforts and costs are required.

It would be nice to make use of the concrete advantages of PUNTOUN and PE PUNTOUN, but it was not really a simple matter how to apply it to the construction of floating structures by using the cast concrete method.

In other words, since the load does not act uniformly in the stepwise construction of the floating structure, the unbalanced load is caused on the Pultun, and the operation for controlling the load can be easily solved, but the self weight is not large, There was no other technology specifically introduced for easy floating structure construction.

1C is a perspective view of a conventional floating dock (Patent No. 10-1302037).

That is, the hull unit 10 includes at least one hollow hole portion 14 penetrating the deck and the bottom of the ship. A plurality of ballast tanks (20) disposed in the hull portion; And a pumping unit installed in the hull unit for supplying seawater to the plurality of ballast tanks or discharging seawater supplied to the plurality of ballast tanks, wherein the pumping units (30, 40) And the seawater is supplied to the hull portion from the bottom of the hull portion along the hollow hole portion 14 passing through the ballast tank adjacent to the central portion of the hull portion among the plurality of ballast tanks, A first pumping unit (30) for supplying the seawater supplied to or supplied to the adjacent ballast tanks; And a second pumping unit (40) installed in the hull unit for supplying seawater from the outside of the hull unit to the ballast tank adjacent to the outer periphery of the hull unit among the plurality of ballast tanks or for discharging the supplied seawater .

In other words, the dock for making the ship is formed as a floating dock. The floating dock is mounted on the floating dock after making the large blocks close to the maximum capacity of the crane on the land, , The seawater is supplied to the ballast tanks of the floating dock to submerge the floating dock below the sea level, and then the completed ship is launched,

Particularly, it is possible to reduce the movement path of seawater by supplying seawater to ballast tanks or discharging seawater from ballast tanks through a hollow hole (14) penetrating the deck and bottom of hull, and to precisely control the amount of seawater So that a stable floating dock can be installed at sea.

As a result, most of the ballast tanks are constructed to be a structure that is advantageous for algae and waves due to seawater in order to construct a ship from a floating dock. Mostly, due to the weight of the ship, ballast tank control of floating dock made of concrete or steel The focus is focused on.

Therefore, the present invention can stably construct a reinforced concrete structure in a river or the sea, and can function as an efficient ballast tank without a large weight, and can be integrated with a floating structure by floating on concrete To provide a method for constructing a buoyant body for a floating floating structure in a safe manner.

To this end,

In the step (a), the segmental buoyant body is a plastic buoyant body formed in the form of a box-shaped body divided by a partition wall, and the on-laying concrete connector body of the same material is connected to a temporary buoyant body And a reinforcing concrete reinforcing member for reinforcing the EPS block to prevent buoyancy caused by being buried in the concrete poured in the step (b) The EPS block disposed on the upper surface of the spotting concrete connection member is embedded in the concrete placed inside the mold installed outside the assembling and mounting buoyancy body, The base plate is formed so that the field-cast foundation plate integrated with the assembling / (B) by using a stiffener to secure the structural rigidity according to the construction of the large floating structure (B).

In addition, preferably, the balance adjustment is performed such that a ballast control pipe is extended to the ballast space (S) in the inner space of the hypothetical buoyancy body in which the inside is formed in the form of a box body divided by the partition wall, so that water is injected into the ballast space (S) Thereby making it possible to adjust the buoyancy structure for the floating structure.

The buoyant body for the floating structure in which the assembly suspended buoyant body according to the present invention and the spotted base plate are integrated with each other can further serve as a first diverging plate for a variety of marine floating structures, It is possible to adjust the balance in waves and adjust the eccentric load due to the construction of the floating structure, and thus it is possible to provide a method of constructing the floating structure for the floating structure capable of constructing the floating structure more quickly and economically.

In addition, the buoyant body for the floating structure according to the present invention can be constructed to construct a buoyant buoyant body for a floating structure by manufacturing and connecting segmented buoyant bodies. Since the segmented buoyant body can be connected easily at sea, it is possible to provide a buoyant body construction method for a floating structure capable of producing a floating body for constructing a floating structure by connecting a segmented buoyant body and connecting it at sea do.

In addition, since the buoyant body for a floating structure for a floating structure is made of cast-in-place concrete, a formwork is required. Such a formwork is installed in a constructional buoyancy buoyancy body and in the casting of concrete, the assembled construction buoyancy body and the poured concrete are integrated So that it is possible to provide a method of constructing a buoyant body for a floating structure in which an artificial concrete connecting member is integrally formed on the upper surface of the assembly suspended buoyant body.

[Buoyancy body for floating structure (A)]

FIG. 2A is a perspective view of a buoyant body A for a floating structure according to the present invention, and FIGS. 2B and 2C are views showing a configuration of a buoyant buoyancy body 100 constituting a buoyant body A for a floating structure according to the present invention. FIG.

The buoyant body A for the floating structure is formed to include the assembled temporary buoyant body 100 and the field mounted base plate 200 in which the spotted concrete connection members 113 are integrally formed as shown in FIG.

As shown in FIG. 2B, the assembling and building buoyant body 100 is assembled to a desired size by assembling a plurality of segmented buoyant bodies 110 and assembling them together in a sea (meaning river or sea).

The segmented buoyant body 110 includes a hypothetical buoyant body 111 and a ballast control pipe 112, both of which are made of a cuboid body.

First, as shown in FIG. 2C, the hypothetical buoyant body 111 in the form of a flat plate box body is a box body formed of a bottom plate 111a, a side plate 111b and an upper plate 111c having a constant thickness. It can be seen that the ballast space S is formed by the upper plate and the ballast space S formed by the upper plate.

When a ballast control pipe 112 having an upper portion extending upward is installed to penetrate the upper plate 111c and the lower portion is exposed to the ballast space S and water is injected through the ballast control pipe 112, The balance adjustment for balancing the water in the ballast space S of the water tank 111 at the sea level becomes possible.

Accordingly, the partition wall 114 is formed in a lattice shape in which the vertical plates intersect with each other, so that the structural rigidity of the hypothetical buoyant body 111 is ensured and the flow of water injected through the through hole 115 is made possible, And the position of the ballast control pipe 112 can be freely selected.

2B and 2C, it can be seen that the ballast control pipe 112 is installed at the right corner of the temporary buoyant body 111. Also, by the ballast control pipe 112 provided at the corner, The injected water can be gradually filled in the whole of the temporary buoyant body 111 through the through hole 115 of the partition wall 114 and is advantageous for balance adjustment.

On the upper surface of the hypothetical buoyant body 111, as shown in FIG. 2A and FIG. 2C, an on-site concrete connection member 113 is integrally formed. It can be seen that such a spotted concrete connector 113 is formed in the form of a beam having a T-shaped cross section according to FIG. 2C.

That is, since the hypothetical buoyant body 111 is a kind of plastic material (polyethylene), when the temporary buoyant body 111 is made of the same material, .

It can be seen that the on-the-spot concrete connection member 113 extends in one direction on the upper surface of the hypothetical buoyant member 111. In this on-site concrete connection member 113, an insertion hole 116 is formed as shown in FIG. 2C So that it is possible to install the concrete reinforcing member 120 such as a reinforcing bar through the through-hole.

Accordingly, the spot-inserted concrete connector 113 functions to integrate the concrete to be poured with the assembly building buoyancy body 100.

As shown in FIGS. 2A and 2B, the segmented and buoyant buoyant members 110 are connected to each other to form a built-up and stacked buoyancy member 100. On the upper surface of the segmented buoyancy member 110, And a concrete reinforcing member 120 such as a reinforcing bar is installed in the on-the-spot concrete connecting member 113.

2A and 3B, the field-placing foundation board 200 is formed by curing a concrete placed inside the workpiece 210 installed along the outer surface of the assembly building buoyancy body 100, And a concrete reinforcing member 120 such as a reinforcing bar, so that the rigidity can be ensured. The mold 210 is finally demoulded.

2A, the EPS block 130 is further installed on the upper surface of the assembled and suspended buoyant body 100, and the EPS block 130 is fixed to the mold by a concrete stiffener 120 such as a reinforcing bar. It is preferable to pour concrete therein to minimize the weight.

As a result, the buoyant body A for the floating structure according to the present invention has a small weight and is easy to assemble and install, and the EPS block 130 is mounted on the upper surface of the assembly building buoyancy body 100, The buried field mounted base plates 200 are integrated with each other to secure a structural rigidity capable of constructing a large floating structure B on the upper surface of the buoyant body A for the floating structure as shown in FIG. It is possible to adjust the balance according to the construction of the large floating structure (B) by using the ballast function of the hypothetical buoyant body (100).

[Flowchart of Construction of Buoyant Body (A) for Floating Structure at Sea]

FIGS. 3A, 3B, 3C, 3D and 3E illustrate a construction flowchart of the buoyant body A for a floating structure according to the present invention.

First, as shown in FIG. 3A, the segmented and buoyant body 110 constituting the buoyant body A for the floating structure is set at sea (steel or sea) and a plurality of segmented buoyant bodies 110 are assembled .

The number of connection of the segmented buoyant body 110 may be determined by a working space in which the floating structure can be installed, and a conventional buoyant buoyancy connecting means may be used for connection to each other. Since the self weight is not large, there are fewer factors of connection defects in connection.

At this time, it can be seen that the ballast control pipe 112 of the assembled segmental buoyant body 110 is arranged to extend upward and is arranged to be gathered at the central portion.

It can be seen that on the upper surface of the assembling and building buoyant body 100, the above-mentioned on-cast concrete connection member 113 is protruded and the on-site concrete connection member 113 and the concrete reinforcement member 120 are constrained to each other .

Next, as shown in FIG. 3B, when the assembling and building buoyancy body 100 is assembled and connected to the segment building buoyancy body 110, the bucket body 210 in the form of a vertical plate is formed outside the assembly building buoyancy body 100, .

In addition, a large number of EPS blocks 130 are disposed above the spot-inserted concrete connecting members 113.

Further, it can be seen that a concrete reinforcing member 120 such as a reinforcing bar is additionally installed to prevent buoyancy generated when the EPS block 130 is buried in concrete. At this time, it can be seen that the ballast control pipe 112 is further extended upward from the upper surface of the mold 210.

Next, as shown in FIG. 3C, concrete is placed in the mold 210 so that the EPS block 130 and the concrete stiffeners 120 are buried in the upper part of the spotting concrete connection member 113, and then the mold 210 is cured It can be seen that the site-casting foundation board 200 integrated with the assembly-building buoyant body 100 can be completed by demoulding the site-inserted concrete joint member 113, (112) is further extended upward from the upper surface of the mold (210).

The buoyant body (A) for a floating structure for a floating structure is provided with an assembling and mounting buoyancy body (100) at a lower portion thereof. A plurality of the segmenting buoyancy bodies (110) are assembled together.

At this time, the site-cast foundation board 200 integrated with the assembling and building buoyancy body 100 can be formed by dividing concrete in consideration of the size of the floating structure B and the like. That is, as shown in FIG. 3D, a die 210 in the form of a vertical plate is further disposed on the outer periphery of the field-placing foundation board 200 integrated with the assembly and building buoyancy body 100. Further, a large number of EPS blocks 130 are additionally disposed on the spotted concrete connection member 113.

Further, it can be seen that a concrete reinforcing member 120 such as a reinforcing bar is additionally installed to prevent buoyancy generated when the EPS block 130 is buried in concrete. At this time, it is also understood that the ballast control pipe 112 is further extended upward from the upper surface of the mold 210.

The EPS block 130 and the concrete stiffeners 120 are then embedded in the upper part of the concrete placement block 113. The concrete block 210 is then finally demolded It can be seen that the field mounted base plate 200 integrally formed with the assembling and building buoyant body 100 can be finally completed by the spotted concrete connection member 113 and the ballast control pipe 200 112 are further extended upward from the upper surface of the mold 210. [

It is a matter of course that it is possible to form the field-place foundation plate 200 by dividing the stage into a single stage or a multi-stage according to the desired thickness of the final spotting foundation board 200.

The ballast control pipe 112 is installed in each of the segmented buoyant bodies 110 so that buoyancy of each segmented buoyant body 110 can be adjusted by injecting water using a pump or the like not shown.

For example, as shown in FIG. 3E, since the construction of the floating structure (B) is sequentially performed as in the first and second layers, a uniform load action is applied to the assembling and building buoyancy body 100 integrated with the site- It is difficult to make additional construction because it is not made to be tilted to the left and balanced.

In the present invention, water is injected into the ballast control pipe (112) by using a pump or the like around the surrounding water (W) to the segment building buoyant body (110) It can be seen that the balance adjustment becomes possible.

That is, the balance is adjusted by adjusting the buoyancy by filling the ballast space S of the segmented buoyancy member 110 divided by the partition with the ballast control pipe 112.

As a result, it can be seen that the construction of the floating structure (B) can be completed in the assembling and building buoyancy body (100) integrated with the final spotting foundation board (200).

[Another embodiment of the buoyancy body (A) for the floating structure for floating structure]

4A, 4B and 4C show another embodiment of a buoyancy structure (A) construction method for a floating structure of the present invention.

First, when a large floating structure with a large size of the floating structure (B) is necessary, the floating structure (A) for the floating structure as shown in FIG. 4A must also be thick or large. It is relatively easy to adjust the size of the assembling and building buoyancy body 100. However, when the field-placing foundation board 200 is made larger, the thickness thereof becomes larger, There is a problem in that the number of times of pouring is increased to make it difficult to make the pouring quickly, and that the weight of the pouring is excessively large.

The present invention particularly optimizes the size of the buoyant body (A) for the floating structure by arranging the reinforcing beam (220) further in the field mounted base plate (200) .

That is, as shown in FIG. 4B, it is known that the steel beam 220a or the precast beam 220b or the like is further provided before the placement of the concrete when the field-cast foundation board 200 is manufactured to form the field foundation foundation board 200 And the installation direction of the reinforcing beams 220 may be longitudinal and transverse directions so as to cross each other so as not to interfere with the EPS block 130.

3B and FIG. 3D, the reinforcing beam 220 is installed together with the EPS block 130 on the upper surface of the spot-inserted concrete connector 113, and the concrete is inserted into the mold after the concrete reinforcement 120 is installed. .

As shown in FIG. 4C, it can be seen that the buoyant body A for the floating structure with the additional reinforcement beam 220 is installed, and that the floating structure B is installed on the buoyant body A for the floating structure. have.
